Re: Drag & Drop - Follow-up Patch

1) I'm not thrilled with when the sheet_order_changed signal is
fired please put it in post_sheet_index_change.

Done. But this function doesn't get called if you reorder the sheets
using drag & drop. That is, the signal won't get emitted and the dialog
from dialogs/dialog-sheet-order.c won't get updated. I don't know what
post_sheet_index_change is for, therefor I can't tell you if the fact
that that function doesn't get called is a bug or not.

2) hmm, removing the arrow when you're not on a label significantly
reduces its utility. Can you rework it to function anywhere within
the control's toplevel window ?
